/**
 * @brief
 *   SdwRectangle: Not like rectangle in SODC, rectagles in Word Pro are
 * defined by 4 points. So they can be any posture in the two-dimensional
 * coordinate system. The class is used to describ such rectangles.
 *	 The foure corner points must be save in menber variable:m_nRectCorner
 * one after another. We assume the input order(the same order in .lwp files)
 * is as below:
 *
 * y ^     m_nRectCorner[3]             m_nRectCorner[2]
 *   |                 |--------------------|
 *   |                 |                    |
 *   |                 |                    |
 *   |                 |--------------------|
 *   |     m_nRectCorner[0]             m_nRectCorner[1]
 *   |
 *   |------------------------------------------------------->
 * (0,0)                                                     x
